未捕获的语法：意外的输入结束likesc.js：0

Question

我试图在缺失的输入上添加{或}的几次尝试。我问了不同的问题，因为我错过了逗号和括号，也有错误的缩进方式。我无法找到此代码中缺少的{或}。

    Parse.Cloud.afterSave("StatusUpdate", function(request) {
  if(request.object.existed()) {
    return;
  }

  // if the user is Undefined
  var toUser = request.object.get("user") ---< **** Line 8 ****
  if (!toUser)
  {
    throw "Undefined toUser. Skipping push for Activity " + request.object.get('StatusUpdate') + " : " + request.object.id;
    return;
  }

  // put Installation query here if needed


  // send notifications based on the StatusUpdate and the passed in user from iOS ---< **** Line 16 ****
  Parse.Cloud.useMasterKey() // depreciated in self hosted parse servers


  // create query based on passed in values
  Parse.Cloud.define("StatusUpdate", function(request, response) {
      //query Installation for user
      var Installationquery = Parse.Object.extend("Installation");
      var query = new Parse.Query(Installationquery);
      var message = request.params.message
      query.equalTo("user", request.params.User);
      query.find({
          success: function(results) {
              response.success("found user" + results)

              // Do something with the returned Parse.Object values
              for (var i = 0; i < results.length; i++) {
                  var object = results[i];
                  Parse.Push.send({
                              where: query, // Set our Installation query
                              data: {

//})

          if (request.object.get("StatusUpdate") === "likedby") {

                  message = request.user.get('postedby') + ': ' + request.object.get('statusOBJID').trim();
              } else {
                  message = "Someone liked on your status update.";
              }

              // Trim our message to 140 characters.
              if (message.length > 140) {
                  message = message.substring(0, 140);
              }

              return message;
          }
        }

您的代码存在的问题：

1. 第1行：无与伦比的'{'。
2. 第7行：缺少分号。
3. 第18行：缺少分号。
4. 第26行：缺少分号。
5. 第30行：缺少分号。
6. 第45行：缺少分号。
7. 第48行：缺少分号。
8. 第76行：缺少分号。
9. 第76行：预期'）'而是看到''。
10. 第76行：缺少分号。

固定：
